Human triggered slab avalanches are possible on steep slopes. At the mid and upper elevations these slides could be triggered on persistent weak layers. At the lower elevations the snowpack has poor structure and slides could fail on a base of well-developed faceted snow. Evaluate the snowpack and terrain carefully.
In steep terrain at the mid and upper elevations skiers and riders could trigger slab avalanches one to three feet in depth. At the lower elevations (below an elevation of 7,500 feet) small pockets of surface slab up to a foot in depth could be human triggered on isolated terrain features.
( Discussion is generated from the previous day's afternoon forecast. )Snowfall will decrease overnight. Skies will be mostly sunny on Friday with temperatures in the 20s and light northerly winds. In areas with poor snow structure unstable snow exists on steep slopes. In these locations recent new snow lies upon a base of well-developed faceted snow. These conditions can be found at the lower elevations and at higher elevations where the snowpack is still fairly shallow. In areas with a deeper snowpack buried persistent weak layers could still be a problem on some steep terrain features. Large slab avalanches with depths to three feet can be triggered by humans on some steep slopes. The general avalanche hazard is moderate. Evaluate terrain and the snowpack carefully.
